小白误闯贵宝地，请各位高见谅。有一问题请大家指教。谢谢了！

请问以下这段是用什么语言写的?
A1:=C>REF(C,4);
NT:=BARSLASTCOUNT(A1);
TJ11:=NT=9;
TJ13:=ISLASTBAR AND BETWEEN(NT,5,8);
AY:=(BACKSET(TJ11>0,9) OR   BACKSET(TJ13>0,NT))*NT;
DRAWTEXT(AY>0,H*1.02,VAR2STR(AY,0)),COLORFF00FF;
DRAWTEXT(NT=9,H*1.02,'9'),COLORGREEN;
B1:=C<REF(C,4);
NT0:=BARSLASTCOUNT(B1);
TJ21:=NT0=9 ;
TJ23:=ISLASTBAR AND BETWEEN(NT0,5,8);
AY1:=(BACKSET(TJ21>0,9)  OR  BACKSET(TJ23>0,NT0))*NT0;
DRAWTEXT(AY1>0,L*0.98,VAR2STR(AY1,0)),COLORFF00FF;
DRAWTEXT(NT0=9,L*0.98,'9'),COLORGREEN;
